Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This is a continuation application based on PCT application
No. PCT/JP2012/56587 filed on Mar. 14, 2012, which claims the
benefit of priority from Japanese Patent Application No.
2011-058089 filed on Mar. 16, 2011, the entire contents of which
are incorporated by reference herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a lever jig which fits a
pair of connectors each other with weak operational force and a
connector apparatus using the same.
[0004] 2. Description of the Related Art
[0005] There have been proposed various connector apparatuses each
of which fits a pair of connectors by operating a lever with weak
operational force (for example, see Japanese Patent Application
Laid-Open Publication No. 2009-187863). Among these connector
apparatuses, there is proposed one having a lever to be detachably
provided on a connector, that is, as a lever jig. With the lever
jig, it is possible to perform the fitting operation for a
plurality of connector apparatuses, thereby aiming at reduction of
the cost of parts, etc. A conventional example of the lever jig and
the connector apparatus using the same is shown in FIGS. 1 to 4.
Description will be made below.
[0006] A connector apparatus 100 has, as shown in FIG. 1, a lever
jig 101, and a female connector 120 and a male connector 130 which
are a pair of connectors.
[0007] The lever jig 101 has, as shown in detail in FIG. 2, a
connector mount portion 102 and a lever body 110 rotatably
supported by the connector mount portion 102. The connector mount
portion 102 has a pair of side walls 103 and a connecting wall part
104 which connects the pair of side walls 103. On the upper ends of
the pair of side walls 103, there are provided upper stopper pieces
103a protruding inside each other.
[0008] Inside the pair of side walls 103, the female connector 120
can be inserted from the bottom side. On the pair of side walls
103, there are provided connector engagement tabs 105 protruding
inside, at a plurality of places, respectively. On the outer
surfaces of the pair of side walls 103, there is provided a pair of
support pins 106 in a protruding manner. On the pair of side walls
103, there are provided a pair of temporary engagement holes 107
and guide slits 108 communicated with the temporary engagement
holes 107. On the pair of side walls 103 and on the lower parts of
the temporary engagement holes 107, there are provided lever
stopper parts 109 in a protruding manner.
[0009] The lever body 110 is provided with a pair of arm parts 111
and an operational part 112 which connects the pair of arm parts
111 at the tips thereof. On the inner surface sides of the pair of
arm parts 111, there is provided a pair of pin reception holes 113.
To the pair of pin reception holes 113, the support pins 106 of the
connector mount portion 102 are inserted, respectively. This
enables the lever body 110 to be operated for rotation around the
pair of support pins 106 between a fitting-operation start position
and a fitting-operation completion position. Inside the pair of arm
parts 111, there is provided a pair of boss introduction grooves
114. The pair of arm parts 111 is provided with temporary
engagement tabs 115 protruding inside, respectively. The lever body
110 has the temporary engagement tabs 115 engaged to the temporary
engagement holes 107 in a position to hit the lever stopper parts
109. The position is the fitting-operation start position for the
lever body 110 (see FIG. 1).
[0010] As shown in FIG. 1, the female connector 120 and the male
connector 130 are provided to be fittable and removable each other.
Both of the female connector 120 and the male connector 130 have
multiple terminals (not shown) and the mutual multiple terminals
(not shown) come in contact in a fitted state. On the upper part of
the female connector 120, there are provided flange parts 121
protruding from the both side surfaces thereof. The male connector
130 has a connector fit chamber 131 with its upper part opened. On
the both side surfaces of the male connector 130, there are
provided a pair of boss parts 132 and a pair of
temporary-engagement release guide ribs 133 in a protruding
manner.
[0011] Next, fitting operation of the female connector 120 and the
male connector 130 will be described. The lever body 110 of the
lever jig 101 is supposed to be set in the fitting-operation start
position. First, from the bottom side of the connector mount
portion 102 of the lever jig 101, the female connector 102 is
inserted. When inserted in a complete-insertion position, the
connector engagement tabs 105 of the connector mount portion 102
are engaged to the flange parts 121 of the female connector 120,
thereby connecting the lever jig 101 and the female connector
120.
[0012] Next, the female connector 120 is inserted into the
connector fit chamber 131 of the male connector 130. Then the
temporary-engagement release guide ribs 133 of the male connector
130 move the temporary engagement tabs 115 to a release position,
thereby allowing the lever body 110 to be operated for rotation.
Also, the pair of boss parts 132 of the male connector 130 is
introduced to the pair of boss introduction grooves 114 of the
lever body 110, thereby setting the female connector 120 and the
male connector 130 in a fitting start position.
[0013] Next, the lever body 110 is operated for rotation from the
fitting-operation start position to the side of the
fitting-operation completion position. Then the pair of boss parts
132 of the male connector 130 moves through the pair of boss
introduction grooves 114 of the lever body 110, so that the male
connector 130 is drawn toward the female connector 120. That is,
the male connector 130 moves to the fitting position side. As shown
in FIGS. 3 and 4, the lever body 110 has its rotational operation
proceeded to come close to the fitting-operation completion
position, so that the upper right-and-left ends of the male
connector 130 hit the connector engagement tabs 105 of the
connector mount portion 102. The lever body 110 is further rotated
from this state to the fitting-operation completion position, so
that the male connector 130 is drawn to the fitting-operation
completion position and each of the connector engagement tabs 105
is moved to the release position. This is the completion of the
fitting operation of the female connector 120 and the male
connector 130. Since each of the connector engagement tabs 105 is
moved to the release position, it is possible to remove the lever
jig 101 from the female connector 120.
[0014] However, for the above-noted conventional lever jig 101 and
the connector apparatus 100 using the same, if the female connector
120 and the male connector 130 incline in a relative position
during the fitting operation, a connector engagement tab 105 on a
side where deeply drawn is moved to the release position in a
position before the fitting-operation completion position. If a
part of the connector engagement tabs 105 is moved to the release
position, the lever jig 101 becomes detachable from the female
connector 120. Accordingly, there is a risk of detaching the lever
jig 101 from the female connector 120 in a half-fitted state
between the female connector 120 and the male connector 130.
SUMMARY OF THE INVENTION
[0015] In view of the foregoing problem, the present invention has
an object to provide a lever jig and a connector apparatus using
the same, which surely prevents a detachment in a half-fitted state
between a pair of connectors.
[0016] The present invention provides a lever jig which is mounted
on one of a pair of connectors and causes fitting force to act on
the pair of connectors by an operation from a fitting-operation
start position to a fitting-operation completion position so as to
move the pair of connectors from a fitting start position to a
fitting completion position, the lever jig comprising: a connector
hold portion that moves between a holding position to hold one of
the connectors and a holding release position to release one of the
connectors from holding; and a lever body that is movably supported
by the connector hold portion and operated between the
fitting-operation start position and the fitting-operation
completion position, wherein the connector hold portion moves in
accordance with an operational position of the lever body, and in a
section between the fitting-operation start position and a position
just before the fitting-operation completion position for the lever
body the connector hold portion moves to the holding position and
in the fitting-operation completion position for the lever body the
connector hold portion moves to the holding release position.
[0017] The connector hold portion includes one which is configured
to include a pair of movable hold parts that moves between the
holding position with a narrowed distance between each other and
the holding release position with a broadened distance between each
other, and an urging means to urge the pair of movable hold parts
to the side of the holding release position, wherein the lever body
has a pair of arm parts movably supported by the pair of movable
hold parts, respectively, both in the holding position and in the
holding release position, and the pair of arm parts has first
contact faces and second contact faces formed thereon,
respectively, to which the pair of movable hold parts comes into
contact by the action of urged force of the urging means, wherein
in a section between the fitting-operation start position and the
position just before the fitting-operation completion position for
the pair of arm parts, the pair of movable hold parts contacts with
the first contact faces to keep the holding position, and in the
fitting-operation completion position for the pair of arm parts,
the pair of movable hold parts contacts with the second contact
faces, thereby moving from the holding position to the holding
release position.
[0018] Another of the present invention provides a connector
apparatus comprising: a pair of connectors to be mutually fittable;
and a lever jig which is mounted on one of the pair of connectors
and causes fitting force to act on the pair of connectors by an
operation from an operation start position to an operation
completion position so as to move the pair of connectors from a
fitting start position to a fitting completion position, wherein
one of the connectors is provided to be held by the lever jig and
detached from a held state, wherein the lever jig includes a
connector hold portion that moves between a holding position to
hold one of the connectors and a holding release position to
release one of the connectors from holding, and a lever body that
is movably supported by the connector hold portion and operated
between a fitting-operation start position and a fitting-operation
completion position, wherein the connector hold portion moves in
accordance with an operational position of the lever body, and in a
section between the fitting-operation start position and a position
just before the fitting-operation completion position for the lever
body the connector hold portion moves to the holding position and
in the fitting-operation completion position for the lever body the
connector hold portion moves to the holding release position.
[0019] According to the present invention, a lever body of a lever
jig is operated from a fitting-operation start position to a
fitting-operation completion position, a connector hold portion
keeps a holding position during operation from the
fitting-operation start position to a position just before the
fitting-operation completion position, and the connector hold
portion moves to a holding release position only after the
completion of operation to the fitting-operation completion
position, thereby the lever jig becomes detachable from one of
connectors. Accordingly, the detachment is not possible in a
half-fitted state between a pair of connectors, thereby surely
preventing the detachment in the half-fitted state between the pair
of connectors.

movement between the protruding connection parts 4a and 4b, thereby
moving in a direction to broaden a distance between each other and
in a direction to narrow a distance between each other. With the
movement, the pair of movable hold parts 4A and 4B moves in
accordance with the following operational position of the pair of
arm parts 11 of the lever body 10, to a holding position to hold
the female connector 20 with a narrowed distance between each other
and to a holding release position to release the female connector
20 from holding with a broaden distance between each other.
Mechanism of movement of the pair of movable hold parts 4A and 4B
in accordance with the operational position of the pair of arm
parts 11 will be described below.
[0039] Both of the protruding connection parts 4a and 4b have
spring reception holes 4c formed on their opposing faces,
respectively. To the both spring reception holes 4c, the coil
spring 5 is received. The coil spring 5 urges in a direction to
broaden the distance between the pair of movable hold parts 4A and
4B, that is a holding release direction.
[0040] On the inner surface sides of the pair of movable hold parts
4A and 4B, there are provided a pair of two lines of protruding
clamp parts 4d in a protruding manner. The pair of protruding clamp
parts 4d is formed along the total length of each of the movable
hold parts 4A and 4B. On the outer surfaces of the pair of movable
hold parts 4A and 4B, there is provided a pair of support pins 6 in
a protruding manner. The pair of support pins 6 is set to a long
dimension enough to keep an inserted-state in pin reception holes

[0042] The lever body 10 includes, as shown in FIGS. 5, 6 and 8,
the pair of arm parts 11 and an operational part 12 which connects
the pair of arm parts 11 at the tips thereof. On the inner surface
sides of the pair of arm parts 11, there is provided the pair of
pin reception holes 13. To the pair of pin reception holes 13, each
of the support pins 6 of the connector hold portion 3 is inserted,
thereby allowing the lever body 10 to be operated for rotation
around the pair of support pins 6 between a fitting-operation start
position and a fitting-operation completion position. Inside the
pair of arm parts 11, there is provided a pair of boss introduction
grooves 14. Each of the boss introduction grooves 14 opens toward a
directly below position in the fitting-operation start position and
in the fitting-operation completion position for the lever body 10.
That is, in the fitting-operation start position and in the
fitting-operation completion position for the lever body 10, boss
parts 32 of the male connector 30 which will be described later,
can be inserted to and removed from the boss introduction grooves
14.
[0043] The pair of arm parts 11 is respectively provided with
temporary engagement tabs 15 protruding inside. The lever body 10
has the temporary engagement tabs 15 engaged to the temporary
engagement holes 7 in a position to hit the lever stopper parts 9.
The position is the fitting-operation start position for the lever
body 10 (see FIGS. 10 and 11).
[0044] To the pair of arm parts 11, outer surfaces of the pair of
movable hold parts 4A and 4B contact by the action of spring force
of the coil spring 5. The pair of arm parts 11 includes a pair of
first contact faces 11a having a narrowed distance between each
other and a pair of second contact faces 11b having a broaden
distance between each other. In a position to contact with the pair
of first contact faces 11a, the pair of movable hold parts 4A and
4B is located in the holding position. In a position to contact
with the pair of second contact faces 11b, the pair of movable hold
parts 4A and 4B is located in the holding release position. Between
the first contact faces 11a and the second contact faces 11b, there
are provided difference faces 11c which are approximately
right-angled. From the fitting-operation start position to a
position just before the fitting-operation completion position for
the pair of arm parts 11, the pair of movable hold parts 4A and 4B
has at least respective parts thereof contact with the first
contact faces 11a, to be in a connector holding position (FIGS. 10
to 13), and in the fitting-operation completion position for the
pair of arm parts 11, the pair of movable hold parts 4A and 4B
comes off the first contact faces 11a and at the same timing has
all the faces come into contact with the second contact faces lib
so as to instantly move from the connector holding position to a
connector holding release position (see FIG. 14).
[0045] As shown in FIG. 5, the female connector 20 and the male
connector 30 are provided to be fittable and removable each other.
Both of the female connector 20 and the male connector 30 have
multiple terminals (not shown) and the mutual multiple terminals
(not shown) come in contact in a fitted state.
[0046] On the upper parts of the both side surfaces of the female
connector 20, there is provided a pair of protruding parts 21 in a
protruding manner. Two lines of protruding parts 21 are provided
along the total length of the side surfaces of the female connector
20. The protruding parts 21 on both sides are positioned so as to
be inserted between the two lines of protruding clamp parts 4d of
the pair of movable hold parts 4A and 4B, so that the female
connector 20 is held with the connector hold portion 3. The clamp
configuration enables the connector hold portion 3 to firmly hold
the female connector 20.
[0047] The male connector 30 has a connector fit chamber 31 with
its upper part opened. On the both side surfaces of the male
connector 30, there is provided a pair of boss parts 32 in a
protruding manner. On the both side surfaces of the male connector
30, there is provided a pair of temporary-engagement release guide
ribs 33 protruding along the lateral direction thereof.
[0048] Next, the fitting operation of the female connector 20 and
the male connector 30 will be described. As shown in FIG. 9, the
lever jig 2 has the lever body 10 positioned in the
fitting-operation completion position and the connector hold
portion 3 positioned in the holding release position. The female
connector 20 is to be located in a space between the pair of
movable hold parts 4A and 4B. Then, while the right and left
protruding parts 21 of the female connector 20 are positioned to be
inserted in the two lines of the protruding clamp parts 4d of the
movable hold parts 4A and 4B, the lever body 10 is operated for
rotation to the side of the fitting-operation start position. Here,
in the fitting-operation completion position for the lever body 10,
the top edges of the pair of movable hold parts 4A and 4B contact
with the difference faces 11c of the pair of arm parts 11.
Accordingly, the pair of movable hold parts 4A and 4B gets over the
difference faces 11c, thereby the lever body 10 rotates to the
fitting-operation start position. The pair of movable hold parts 4A
and 4B gets over the difference faces 11c to change contact faces
to the first contact faces 11a, thereby the pair of movable hold
parts 4A and 4B is moved to the holding position.
[0049] As shown in FIG. 10, in the fitting-operation start position
for the lever body 10, the pair of movable hold parts 4A and 4B is
positioned in the holding position so as to hold the female
connector 20. This allows the female connector 20 to be positioned
by the connector hold portion 3 and not to be detached from the
connector hold portion 3. In the fitting-operation start position,
the temporary engagement tabs 15 of the lever body 10 are engaged
to the temporary engagement holes 7 of the connector hold portion
3, thereby the lever body 10 is temporarily stopped at this
position. This is the completion of setting the female connector 20
to the lever jig 2.
[0050] Next, as shown in FIG. 11, to the connector fit chamber 31
of the male connector 30, the female connector 20 is inserted. With
the insertion, the pair of boss parts 32 of the male connector 30
gets into the pair of boss introduction grooves 14 of the lever
body 10, thereby the female connector 20 and the male connector 30
are set in the fitting-starting position. The temporary-engagement
release guide ribs 33 of the male connector 30 move the temporary
engagement tabs 15 of the lever body 10 to a release position,
which allows the lever body 10 to be operated.
[0051] Next, as shown in FIG. 12, the lever body 10 is operated to
rotate from the fitting-operation start position to the side of the
fitting-operation completion position. Then the pair of boss parts
32 of the male connector 30 moves through the pair of boss
introduction grooves 14 of the lever body 10, thereby the male
connector 30 is drawn to the female connector 20. That is, the male
connector 30 moves to the fitting position side.
[0052] Here, as the operational position of the lever body 10 comes
close to the fitting-operation completion position, an area where
the pair of movable hold parts 4A and 4B contacts with the first
contact faces 11a of the arm part 11 gradually becomes smaller.
Then, as shown in FIG. 13, when it comes to the position just
before the fitting-operation completion position, the pair of
movable hold parts 4A and 4B only has their one edges contact with
the first contact faces 11a. Still, the pair of movable hold parts
4A and 4B has at least a part contact with the first contact faces
11a, so as to receive a restriction from the pair of first contact
faces 11a, thereby keeping the holding position.
[0053] As shown in FIG. 14, when the lever body 10 is rotated to
the fitting-operation completion position, the male connector 30 is
drawn to a fitting completion position. Also, when the lever body
10 reaches the fitting-operation completion position, the pair of
movable hold parts 4A and 4B first comes off the first contact
faces 11a of the arm part 11 and moves its contact position to the
second contact faces 11b by the spring force of the coil spring 5.
That is, the pair of movable hold parts 4A and 4B moves to the
holding release position first at the fitting-operation completion
position for the lever body 10. This allows the lever jig 2 to be
detached from the female connector 20. As shown in FIG. 15, the
lever jig 2 is detached from the female connector 20, thereby the
connector fitting work is completed.
[0054] As described above, the lever jig 2 has the connector hold
portion 3 which moves between the holding position to hold the
female connector 20 and the holding release position to release the
female connector 20 from holding, and the lever body 10 which is
movably supported by the connector hold portion 3 and operated
between the fitting-operation start position and the
fitting-operation completion position, wherein the connector hold
portion 3 moves in accordance with the operational position of the
lever body 10, and in a section between an operation
fitting-operation start position and a position just before the
fitting-operation completion position for the lever body 10, the
connector hold portion 3 moves to the holding position and in the
fitting-operation completion position for the lever body 10, the
connector hold portion 3 moves to the holding release position.
[0055] Accordingly, the lever body 10 of the lever jig 2 is
operated from the fitting-operation start position to the
fitting-operation completion position, and during the operation
from the fitting-operation start position to the position just
before the fitting-operation completion position the connector hold
portion 3 keeps the holding position and only after the operation
is completed in the fitting-operation completion position the
connector hold portion 3 moves to the holding release position,
thereby allowing the lever jig 2 to be detachable from the female
connector. Accordingly, when the female connector 20 and the male
connector 30 are in a half-fitted state, the detachment is not
possible, thereby surely preventing the detachment in a half-fitted
state between the female connector 20 and the male connector
30.
[0056] The connector hold portion 3 has the pair of movable hold
parts 4A and 4B which moves between the holding position with a
narrowed distance between each other and the holding release
position with a broadened distance between each other and the coil
spring 5 as an urging means, which urges the pair of movable hold
parts 4A and 4B to the holding release position side, and the lever
body 10 has the pair of arm parts 11 which is rotatably supported
by the pair of movable hold parts 4A and 4B both in the holding
position and in the holding release position, wherein the pair of
arm parts 11 has the first contact faces 11a and the second contact
faces 11b formed thereon, to both of which the pair of movable hold
parts 4A and 4B comes into contact respectively by the action of
spring force of the coil spring 5, wherein in a section between the
fitting-operation start position and the position just before the
fitting-operation completion position for the pair of arm parts 11,
the pair of movable hold parts 4A and 4B contacts with the first
contact faces 11a to keep the holding position, and in the
fitting-operation completion position for the pair of arm parts 11,
the pair of movable hold parts 4A and 4B contacts with the second
contact faces 11b, thereby moving from the holding position to the
holding release position. Accordingly, the structure for moving the
connector hold portion 3 in accordance with the operational
position of the lever body 10 is realized by a less number of
parts, which are the pair of movable hold parts 4A and 4B, the coil
spring 5 as the urging means and the pair of arm parts 11, and a
simple configuration.
[0057] On completion of the fitting work of the lever jig 2, as
shown in FIG. 15, the lever body 10 is located in the
fitting-operation completion position. In the fitting-operation
completion position for the lever body 10, the pair of movable hold
parts 4A and 4B has their upper ends contact with the difference
faces 11c of the pair of arms 11, so that the pair of arm parts 11
is temporarily locked at the fitting-operation completion position.
Accordingly, it is convenient for the next connector fitting
work.
